4 Ways to Format a Number Without Decimals in Oracle

How to Format a Number with a Comma in Oracle
When you use the TO_CHAR() function to format a number in Oracle, you use a format model to determine how the number should be formatted.
For example, you could format a number like 12,345.00 or like 12.345,00, depending on your locale.
